SetRowCompressed(IntPtr,IntPtr,int,int) Method

Summary

Puts one or more rows of 1-bit compressed data from an unmanaged memory buffer to an image that is maintained in its compressed format.

Syntax

C++/CLI

Java

Python

public void SetRowCompressed( 
   IntPtr workBuffer, 
   IntPtr runBuffer, 
   int row, 
   int lines 
)

public void setRowCompressed( 
  byte workBuffer[],  
  short runBuffer[],  
  int row,  
  int lines 
)

public: 
void SetRowCompressed(  
   IntPtr workBuffer, 
   IntPtr runBuffer, 
   int row, 
   int lines 
)

def SetRowCompressed(self,workBuffer,runBuffer,row,lines):

Parameters

workBuffer
Pointer to unmanaged memory optional work buffer. Allocating the work buffer speeds processing if you call this method more than once, because if you do not allocate a work buffer, the method allocates and frees a temporary buffer each time it is called. The size of this buffer should be the same as the image's BytesPerLine property. Pass IntPtr.Zero to runBuffer if you do not want to use a work buffer.

runBuffer
Input buffer, which contains 1-bit compressed image data.

row
Number of the first row to update.

lines
Number of rows to update.

Remarks

This method is available in the (Document/Medical only) Toolkits.

This method is useful for working with 1-bit images that are loaded in their compressed formats for faster loading and display.
